Marin County

Plumber in Kentfield, CA

CNTRline Plumbing serves Kentfield, from the gated estates up in Kent Woodlands at the base of Mount Tamalpais down to the flats near Bon Air and the College of Marin. These are big properties with long runs of pipe, and we show up ready for that. We travel from Rohnert Park and cover the whole Ross Valley end of central Marin.

Plumbing in Kentfield

Kent Woodlands homes sit on wooded hillsides with mature oaks and long private driveways, so the sewer laterals run far and tree roots find every crack. Many of these houses are large mid-century estates with plumbing that has been added onto over the years and does not always match. Down in the flats, the ground stays wet and older water heaters and pressure regulators wear out faster.

On the long buried laterals common in Kent Woodlands, our video inspection finds the exact root intrusion or break instead of guessing where to dig.

Neighborhoods we cover: Kent Woodlands, Bon Air, Kentfield Flats, College of Marin.

ZIP codes: 94904.

Questions

Common questions from Kentfield homeowners

It can. Kentfield sits in the Ross Valley Sanitary District, and compliance is triggered by a remodel over $75,000 or by adding a bathroom, not only by a sale. Get the lateral scoped early, because a failed line found in the middle of a remodel is the kind of thing that stalls the whole job.
Yes. California requires seismic strapping and a thermal expansion tank on water heater installs, and we do both as part of the job in Kentfield rather than as an add on. A tank replacement generally runs $1,800 to $3,600 installed and a tankless conversion $4,500 to $9,000. Call (707) 308-5599 for a free quote on the swap.
All of it, from Novato at the north end down through Kentfield and Greenbrae to Mill Valley and Sausalito. Our shop is at Raley's Town Center in Rohnert Park and we drive Highway 101 into Marin every week, so no part of the county is a special trip for us. We cover Sonoma County the same way.
